Huawei 2103054885 BBU3900/BBU3910/BBU5900 Telecom System Card / Module

The Huawei 2103054885 is a UMPTb1, a Universal Main Processing and Transmission (UMPT) board for Huawei’s BBU3900, BBU3910 and BBU5900 baseband units. It is the main control board of the base station: it manages the other boards in the BBU, processes signalling, handles the transmission interfaces and provides clock synchronisation. The UMPT supports GSM, WCDMA and LTE and sits in the BBU alongside the baseband (UBBP/WBBP) boards, connecting the radio access network to the core network. The ‘b1’ revision sits within the wider UMPTb sub-family alongside other Tech-Star stock such as UMPTb2, UMPTb3 and UMPTb9, all sharing the same core main-control function with incremental hardware revisions. As with all UMPT boards, correct hardware and firmware revision matching to the host system’s software baseline is essential before fitting. As Huawei base station hardware, it remains in demand for maintaining and expanding installed networks. Tech-Star (UK-based, shipped worldwide) supplies this unit tested and ready to deploy.
